这套源码围绕“笔”的顶底识别展开，用BACKSET与SUMBARS回溯笔的转折位置，再通过VALUEWHEN取最近两笔的高低点来框定中枢上下沿（ZG/ZD）。图上标注的“进”“反”“低”“高”均为结构满足条件时的文字提示，属于形态识别类参考，不构成任何操作建议。
使用说明：仅供学习参考
1、先看ZG与ZD是否画出。源码中L1缠与L2缠的VALUEWHEN比较决定了ZD取值，H1缠与H2缠决定ZG，两条虚线出现后才存在可参考的区间边界。
2、关注“进”与“反”的出现位置。“进”仅在C>ZD&&C<ZG且处于向下笔转折点时标注，“反”则对应向上笔转折点且同样落在区间内，两者都依赖BACKSET锁定最后一笔的位置。
3、留意BACKSET与REFX1的引用特性。源码中大量使用BACKSET(ISLASTBAR,...)将信号回溯到历史K线，以及REFX1(...,9999999)向未来取值，这类写法在历史图上会随最新数据变化而调整显示位置，属于正常的公式回看机制。
4、下跌中与上涨中的“低”“高”标注条件不同。“低”要求下跌中且向下笔转折时前高低于ZG，“高”要求上涨中且向上笔转折时前低低于ZG，可对照BARSLAST的比较结果理解方向判定逻辑。
